rear view. System unit electronics and peripherals contain (or may be upgraded to
contain) the following features:
Tower enclosure with 350-watt power supply.
Support for modular UltraSPARC II processor with up to a 4-megabyte (Mbyte)
Ecache and system operating frequencies from 100 megahertz (MHz) to 400 MHz.
83.3-MHz to 120-MHz UPA coherent memory interconnect.
Use of dual in-line memory modules (DIMMs). Each group of four DIMM slots
accepts 16-, 32-, 64-, or 128-Mbyte DIMM modules. Populating with four identical
capacity DIMMs enables the memory controller for optimal system performance.
There are a total of 16 DIMM slots.
Four PCI slots: three 33-MHz, 64-bit or 32-bit, 5 Vdc slots; one 66-MHz or
33-MHz, 64-bit or 32-bit, 3.3 Vdc slot
Two UPA graphics slots.
10-/100-megabits per second Ethernet.
40-Mbytes per second UltraSCSI.
Two DB25 serial ports (synchronous and asynchronous protocols).
Centronics-compatible parallel port interface with extended capability port (ECP)
support.
Modular audio interface.
Second 3.5-inch drive bay
